About this deal

The cache clearly does not help enough to give the Ryzen 9 7950X3D the performance advantage in any other CPU test in our suite. At the same time, its lower TDP and heat limit cause the 7950X3D to operate a bit slower and perform worse in almost every test except that one. The Ryzen 9 7950X is slightly faster in many of these tests, but, considering how much cheaper that chip is at list price, it’s a bit of a no-brainer which is the better value in this scenario.

When it comes to the Intel Core i9-13900K, it too outperforms the 7950X3D in single core performance, with the 7950X3D running about 12% slower than the 13900K on average. The difference between the two tightens on multicore performance, with the 7950X3D running about 5% slower in multicore on average. The lower power consumption measured during Adobe Premiere and Cinebench gives the Ryzen 9 7950X3D better overall performance per watt and slightly better overall energy efficiency. This is hurt by the high idle power consumption, however, which never drops below 97W with the system sitting idle at the desktop for prolonged periods. This latter issue may be resolved with a BIOS or driver update, though.

The Hitches in AMD's Plan

Speaking of performance — boy howdy, this is a hell of a processor. It doesn't always hit the highest score on a given test, and it can often lag 5% to 10% behind the 7950X or i9-13900K on a few synthetic CPU benchmarks like CineBench R23 or Geekbench 5, but that could be chalked up to the pre-release BIOS and chipset drivers I used for testing. Even if that isn't the case, nobody buys a processor to run artificial test suites on it. The score in 3DMark obtained by the Ryzen 9 7950X3D is slightly lower than the one obtained by the Ryzen 9 7950X, but by so slim of a margin that it's essentially a tie. These two chips tie in other tests as well but, in F1 22, the Ryzen 9 7950X3D holds a decisive advantage over its similarly named counterpart while also narrowly passing the Intel competition. After traditional levers have been twiddled and optimised to the nth degree, out-the-box thinking is required to increase performance without resorting to the age-old, sledgehammer technique of slamming as much power through the best CPU as possible. AMD believes it has uncovered a gem in X3D technology. First seen on Ryzen 7 5800X3D, the latest 7000 Series range is receiving cache-enriched upgrades to not one but three processors. Ryzen 9 7950X3D and Ryzen 9 7900X3D stride forward today, with Ryzen 7 7800X3D arriving April 6. Leveraging the same technology we first witnessed with the impressive Ryzen 7 5800X3D, suffusing more L3 cache is inherently more difficult on two-CCD processors such as the review Ryzen 9 7950X3D and 7900X3D. The asymmetrical design and restrained power budget work well enough to deliver the same level of overall gaming performance as MadWattage™ Core i9-13900KS, which is a feat in itself.

AMD Ryzen 9 7950X3D review: Team Red retakes the lead with

Our Services Delivery Information Warranty Information Terms & Conditions WEEE Policy Finance Options Business & Education To be clear (and contrary to our earlier theorizing that we mentioned in the Editors' Note up top), the Ryzen 9 7950X3D's IGP doesn't have access to the L3 cache on the processors, but just like the 3D V-Cache can help gaming performance with a graphics card, it can help the IGP perform better in the right scenarios, too. If the IGP did have access to the L3 cache, we would expect to see an even more pronounced performance boost, and the idea of seeing a future Ryzen 7000-series APU, a processor with a relatively powerful IGP and the 3D V-Cache together, would be exciting. That's not what this is, though. System Power and Thermals No responsibility is taken for the correctness of this information. The listed offers do not constitute legally binding advertising claims of the merchants. The Ryzen 9 7950X3D pretty much matches the 7950X in Blender and Adobe Photoshop and Adobe Premiere tests, though it lags a bit in VRay 5 (though not by that much). Where it really shines though is with HandBrake 1.6. This is one of the creative tests we use where we get to measure it's true real-world performance on a creative workload, especially one that is highly CPU dependent. Looking into further games reveals 7950X3D doesn’t have the benchmark wow factor of 5800X3D. That’s because Intel’s latest Raptor Lake architecture has moved the gaming needle to the right, limiting X3D’s comparative gains.Derived by dividing the same multi-core score by recommended pricing, value, too, is okay given how much application and gaming performance is on offer.

Currently the best processor in Intel's arsenal, the i9-13900K is no joke. In terms of raw performance, it goes pound for pound with the best AMD processors and does so at a lower retail price.

Extracting more performance from CPUs is an inherently complicated business. Increasing frequency burns power, going architecturally wider burns die size, jumping down successive manufacturing nodes is damn expensive. Who’d be a CPU lead architect? New problems arise faster than extant ones are solved. Fundamental limitations ought to encroach on step-change improvements from one generation to the next, yet AMD and Intel continue to deliver in spades. Today’s best Ryzen 9 and Core i9 chips smash predecessors from merely three years’ ago. In Darth’s seminal words, ‘impressive, most impressive.’ We’re curious as to why AMD restrained power so much when a 170W TDP and associated 220W PPT is fine for 7950X. Is it really a case of ensuring an extra 64MB of L3 cache doesn’t overheat, or is there something more sinister going on? Putting our conjecturing hat on, equipping X3D with the standard 170W TDP would make regular 7950X redundant. Product positioning and all that.

The amount of cache on CPUs has grown over time usually by very small steps, but there have also been a few times when AMD and Intel have significantly jumped up the amount of cache in an effort to boost performance. These efforts in the past have seen mixed results with, at the best of times, a modest performance gain occurring and, at the worst of times, nothing really changing. In part, the mixed results are due to software development, as apps need to be explicitly programmed to take advantage of the added cache for a noticeable improvement to occur.
